Abstract

Freshwater fungi are highly diverse in China and frequently reported from submerged wood, freshwater insects, herbaceous substrates, sediments, leaves, foams, and living plants. In this study, we investigated two freshwater species that were collected from Yunnan and Guizhou provinces in China. Detailed morphological analysis complemented by multi-gene phylogenetic analyses based on LSU, SSU, ITS, RPB2 and TEF1-α sequences data revealed them to be two new saprobic species, namely Acrogenosporaalangiisp. nov. and Conioscyphayunnanensissp. nov. in their asexual morphs. Additionally, Acrogenosporaalangiisp. nov. is reported for the first time as a freshwater ascomycete associated with the medicinal plant Alangiumchinense (Alangiaceae). Detailed morphological descriptions, illustrations and updated phylogenetic relationships of the new taxa are provided herein.

来自中国西南部的两种新型淡水接合菌：Acrogenospora（Minutisphaerales，Dothideomycetes）和Conioscypha（Conioscyphales，Sordariomycetes）。

淡水真菌在中国种类繁多，经常被报道来自沉水木材、淡水昆虫、草本基质、沉积物、叶片、泡沫和活体植物。本研究调查了从中国云南省和贵州省采集的两种淡水真菌。通过详细的形态分析以及基于 LSU、SSU、ITS、RPB2 和 TEF1-α 序列数据的多基因系统发育分析，发现它们是两个无性生殖的新物种，即无性形态的 Acrogenosporaalangiisp.nov.和 Conioscyphayunnanensp.nov.。此外，Acrogenosporaalangiisp.nov.首次被报道为与药用植物Alangiumchinense（Alangiaceae）相关的淡水子囊菌。本文提供了新分类群的详细形态描述、插图和最新的系统发生关系。
